Stormwater Management
What is the National Pollutant Discharge Elimination System (NPDES) Storm Water Program?
Mandated by Congress under the Clean Water Act, the NPDES Stormwater Program is a comprehensive two-phased national
program for addressing the urbanized sources of storm water discharges that adversely affect the quality of our
nation’s waters. Phase I of the regulations was initiated in the early 1990’s for municipal separate storm water
systems serving over 100,000 in population. The NPDES Phase II Program extends this program to all remaining urbanized
communities. The program uses the NPDES permitting process to require the implementation of Minimum Control Measures
designed to prevent harmful pollutants from being washed by storm water runoff into local water bodies.
Minimum Control Measures:
1. Public Education and Outreach

2. Public Participation and Involvement
3. Illicit Discharge Detection and Elimination
4. Construction Site Stormwater Runoff Control
5. Post-Construction Stormwater Runoff Control
6. Pollution Prevention and Good Housekeeping
